Add eight cups of distilled or purified water in a sauce pan and boil it.
Add one ounce each of dried sage, dried rosemary and dried nettle to the hot water. Then add two ounce of black walnut shells to the mixture of herbs.
Take two regular tea bags, open them up and add their contents to the hot water mixture. Tightly close out the sauce pan and let the contents steep for at least three hours. Be careful not to over-cook the contents and don’t exceed to four hours.
Once the mixture is fully steeped, strain it through a thin piece of cloth or net.
Add two table spoons of jojoba oil into the hot contents and mix it well. Put the contents in a jar and store in the refrigerator.
Shampoo your hair properly, rinse and then dry them up with a towel. Shake the bottle of the hair dye you made and apply half cup of it directly onto your hair. Massage it into your head scalp for a minute and then squeeze out the excess dye remaining in your hair. Make sure to wear gloves because hair dye can stain your hands easily. Rinse your hair when it fully dries up.
Mix one quarter of walnut hair dye with the same amount of shampoo and use it regularly to maintain your hair colour.
